The RCBS Trim Pro 3-Way Pilot/Chamfer (RCBS part no. 90271) is a caliber-specific pilot built for the RCBS Trim Pro Case Trimmer 3-Way Cutter, sized here for .375 caliber brass. Reloaders who process a lot of once-fired brass rely on this pilot to hold each case firmly in place while the cutter does its work, keeping trims consistent from case to case. Instead of running three separate tools, the 3-Way head combines trimming, chamfering, and deburring in a single station on your bench. It is a straightforward, purpose-built accessory for anyone serious about case prep ahead of a precision rifle load.

Key Specifications

• Sized for .375 caliber brass, matching the pilot to the exact case neck diameter it is trimming.
• Features a three-blade cutting head that trims, chamfers, and deburrs the case mouth in one continuous operation.
• Built to mount directly on the RCBS Trim Pro Case Trimmer 3-Way Cutter, so no separate adapters are needed.
